Answer:
%∆C = 249.22%
the percentage increase in the cost of his car insurance is 249.22%
Step-by-step explanation:
Given;
Cost of car insurance last year C1 = £256
Cost of car insurance this year C2 = £894
Percentage increase = change in cost/initial cost × 100%
%∆C = ∆C/C1 × 100%
%∆C = (C2-C1)/C1 × 100%
Substituting the given values;
%∆C = (894-256)/256 × 100%
%∆C = 249.21875%
%∆C = 249.22%
the percentage increase in the cost of his car insurance is 249.22%
